General description
Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol<TMSYMBOL></TMSYMBOL> solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol<TMSYMBOL></TMSYMBOL> solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified.
Application
- Quantitative determination of nitrous oxide in human blood by HS-GC-MS: forensic application of two fatal poisoning cases.: This study leverages n-Pentane in headspace gas chromatography-mass spectrometry (HS-GC-MS) for the forensic analysis of nitrous oxide in human blood. Highlighting its importance in forensic science, the research demonstrates n-Pentane′s utility in providing accurate and reliable measurements essential for legal and medical evaluations (Li Z et al., 2024).
